Question 8

Immersive live experience systems and services

(New Question)

Motivation
Recently, some of huge sport events and music concerts are not only broadcasted, but also delivered to remote sites for public viewing or live viewing in order to share emotion by audiences in remote sites as if they were in main event venues. In order to provide high-realistic sensations to audiences at remote sites, immersive live experience (ILE) needs to be implemented to reconstruct event sites virtually with presentation of real-sized objects and sound direction by transmitting environmental information together with audio and video streams.
Implementing ILE needs several technologies such as real-time objects extraction technologies at event sites, spatial location sensing technologies for objects, sound direction identify technologies, media transport technologies for extracted objects including spatial location information, presentation technologies including 3D projection at remote sites, synchronous technologies with video, sound and lighting, and so on. Although some of them are already established, there are some conditions and/or limitations such as specific content and pre-arrangement of remote sites. Pre-arrangement of remote sites includes 3D projection mapping, and takes much time for adjustment terminal devices. In addition, these technologies have not systemized, and most of them are not standardized yet.

In order to share enthusiasm at event venues with large audiences even if they are in remote sites far from event venue, implementing immersive live experience services based on standardized designs is desired. By standardizing ILE in ITU‑T, it is expected that audiences anywhere in the world can cheer their favourite sport teams or artists at remote sites even if they are not in the event venue, and they can feel a sense of togetherness and get passionate as if they were in the event venue. Most of these technologies are related to the multimedia studies in Study Group 16, thus this Question will progress standardization activities of ILE.

Globally interoperable standards will activate a market for the ILE systems and services. This Question will cover all relevant work items on multimedia aspects of immersive live experience systems and services.
